Also break some long lines, remove codec function placeholder comments
and add spaces in sample/pixel format lists.

The A32 bitstream reader variant is only used on ARMv5 and for
Prores due to the larger bit cache this decoder requires.
In benchmarks on ARMv5 (Marvell Sheeva) with gcc 4.6, the only
statistically significant difference between ALT and A32 is
a 4% advantage for ALT in FLAC decoding. There is thus no (longer)
any reason to keep the A32 reader from this point of view.
This patch adds an option to the ALT reader increasing the bit
cache to 32 bits as required by the Prores decoder. Benchmarking
shows no significant change in speed on Intel i7. Again, the
A32 reader fails to justify its existence.

These windows do not really belong in fft/mdct files and were
easily confused with the similarly named tables used by rdft.

This removes the rather pointless wrappers (one not even inline)
for calling the fft_calc and related function pointers.

It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

None of these symbols should be accessed directly, so declare them as
hidden.

Conversion of an out of range float to int is undefined. Clipping to
the final range first avoids such problems. This fixes decoding on
MIPS, which handles these conversions differently from many other CPUs.

Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

These macros are redundant. All uses are replaced with the generic
DECLARE_ALIGNED macro instead.

AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.

Otherwise doxygen complains about ambiguous filenames when files exist
under the same name in different subdirectories.
